General
Colour	Black

The Helavia DA 185/250/40 black is a cable gland made of polychloroprene rubber, manufactured by Ses-Sterling, and is used for the secure and tight routing of cables or lines through components such as enclosures, wall penetrations, or switch boxes. This rubber gland is specifically designed for use in electrical and installation technology, where mechanical protection and sealing against dust and moisture are required. The gland is supplied in a package of 100 pieces and is black in colour, making it suitable for use in industrial and technical environments.

Applications

The cable gland DA 185/250/40 is typically used in electrical installation, machine building, and building technology, where cables must be routed through wall or ceiling penetrations. It protects the lines from mechanical stresses such as friction, pressure, or bending, and simultaneously prevents the ingress of dust, moisture, or other environmental influences. The gland is particularly suitable for applications requiring high mechanical strength and chemical resistance, for example in production plants, automation technology, or utility and waste management technology.

Functions and Features in Detail

The gland is made of polychloroprene rubber, an elastic, durable material that offers high flexibility and resistance to weathering, UV radiation, and chemical substances. The shape of the gland allows for a secure and tight fit in holes with a diameter of 185 mm to 250 mm, with an inner diameter for cable routing of 40 mm. The black colour is not only aesthetically neutral but also typical for technical components used in industrial environments. The gland is supplied in a pack of 100 units, making it suitable for larger installations or series assembly.

Technical Explanation

The construction of the gland is based on an elastic, ring-shaped profile that is inserted into a hole and ensures a tight fit. The elastic properties of the polychloroprene rubber allow for adaptation to slight irregularities in the hole and ensure a secure hold. The inner surface is designed so that cables or lines can be routed through without damage. The gland thus serves as a mechanical protection and as a sealing element that prevents the ingress of foreign objects or moisture. The material selection ensures a long service life even under demanding conditions.

Compatibility and Accessories

The gland is designed for holes with a diameter range of 185 mm to 250 mm and allows the routing of cables with a maximum diameter of 40 mm. It is compatible with standard installation techniques and can be used in conjunction with other components such as switch boxes, wall penetrations, or machine enclosures. Installation requires no additional tools or mounting aids; the gland is simply inserted into the designated hole and holds securely due to elastic tension.

Installation and Mounting

Mounting is done by simply inserting the gland into the designated hole. The elastic shape ensures a secure fit without additional fastening elements. The gland is dimensioned to be easily pushed into the hole and forms a tight seal. Installation requires no special tools and can be carried out even by skilled workers without special equipment. The gland is designed for use in static applications where no dynamic movements of the cables occur.

Operational Advantages

Using the Helavia DA 185/250/40 black provides reliable mechanical protection for cables and lines. The sealing effect protects the installation from environmental influences, extending the service life of the lines and increasing operational safety. The material strength and chemical resistance of the polychloroprene rubber ensure a long service life even in demanding environments. The gland is easy to install and requires no additional mounting aids, reducing installation time and making work processes more efficient.
